Some rather annoying game teleports (such as when you trample farmland, enter a boat/minecart or buggy Minecraft behavior that results in teleports) are no longer recorded. Additionally, the backlist can now be cleared with teleporting via /back. You can now use /backlist [number of steps] clear to clear your backlist by the given number of steps. Additionally, if you have an error in your command syntax, you'll get more detailed feedback on that.
